How to choose an energy storage motor

Devices from compressors to flywheels could be revolutionized if electric motors could run at higher speeds without getting hot and failing. MIT researchers have now designed and built novel motors that promise to fulfill that dream. Central to their motors are spinning rotors of high-strength steel with no joints or bolts.

Designing a motor to turn electricity into movement is tricky. In a typical motor, a component called a rotor turns inside a stationary component.

To Mohammad Imani-Nejad PhD ’13, Trumper’s graduate student and now a postdoctoral associate in the MIT Laboratory for Manufacturing and Productivity, the solution was to get rid of the permanent magnets.

With any motor, a major challenge is designing the coils and the currents they carry to create the magnetic fields needed to control the rotor.

The photo to the right shows the first setup they built. It consists of a rotor sandwiched between two stators, top and bottom. Four sensors entering from the top monitor the position of the rotor. Key Takeaways:Choose the right electric motor by considering power requirements, motor types, efficiency, and environmental impact. Balance performance and cost for optimal results in your application.Prioritize noise and vibration levels, energy efficiency, and environmental compliance when selecting an electric motor.

6 FAQs about [How to choose an energy storage motor]

Why do electric motors need more energy management strategies?

Since the electric motor functions as the propulsion motor or generator, it is possible to achieve greater flexibility and performance of the system. It needs more advanced energy management strategies to enhance the energy efficiency of the system.

What are the different types of energy storage systems?

Classification of different energy storage systems. The generation of world electricity is mainly depending on mechanical storage systems (MSSs). Three types of MSSs exist, namely, flywheel energy storage (FES), pumped hydro storage (PHS) and compressed air energy storage (CAES).

What are energy storage systems?

Energy storage systems (ESSs) are the technologies that have driven our society to an extent where the management of the electrical network is easily feasible.

Can small applications be used instead of large flywheel energy storage systems?

Small applications connected in parallel can be used instead of large flywheel energy storage systems. There are losses due to air friction and bearing in flywheel energy storage systems. These cause energy losses with self-discharge in the flywheel energy storage system.

Which type of motor is suitable for EVs?

These types of motors are suitable for HEVs, which involves various speed ranges and high starting torque from the Integrated Stator Generator. In contrast, the VPM motor is preferable to in-wheel direct drive EVs owing to its low-speed profile with high torque density.

Why do flywheel energy storage systems have a high speed?

There are losses due to air friction and bearing in flywheel energy storage systems. These cause energy losses with self-discharge in the flywheel energy storage system. The high speeds have been achieved in the rotating body with the developments in the field of composite materials.
